What is NPT?

The acronym NPT stands for Non-Proliferation Treaty. The NPT is an international treaty on the Non-Proliferation of Nuclear Weapons and Nuclear Technology.

The signatories, which are non-nuclear-weapon states agreed to never acquire nuclear weapons, and the signatories, which already have nuclear weapons, agreed to share the benefits of peaceful nuclear technology with other countries.

South Africa is the only country that developed nuclear weapons by itself and later dismantled them.

The former Soviet states Ukraine, Belarus, and Kazakhstan, which inherited nuclear weapons from the former USSR, dismantled them and declared themselves as non-nuclear-weapon states.

India has not signed the NPT till now because NPT only recognizes the countries that had tested nuclear weapons before 1967. If any country signs the treaty, it will not be considered a nuclear weapon state. In 2007, in Tokyo, then India's external affairs minister Pranab Mukherjee said that "If India did not sign the NPT, it is not because of its lack of commitment for non-proliferation, but because we consider NPT as a flawed treaty and it did not recognize the need for universal, non-discriminatory verification and treatment."
